The Biology portion has three units. Here is a unit-wise detailed breakup of all chapters:
ICSE class 10 Biology syllabus Unit 1: Basic Biology
This section includes chapters 1, 2 and 3 of the ICSE Class 10 Biology syllabus. This unit is based on the study of cells and Genetics. Chapter 1 includes concepts such as the structure of the cell, its organelles and the nucleus. Topics such as the structure of chromosomes, genes, and the process of meiosis and mitosis are explained in chapter 2. The genetics chapter includes the study of the three Mendel’s laws, sex determination genes, genotype and phenotype.
ICSE class 10 Biology syllabus Unit 2: Plant Physiology
Chapters 4, 5, 6, and 7 are included in this unit. In chapter 4, topics like characteristics of roots, absorption and conduction, root pressure and more are explained. Chapter 5 revolves around transpiration, factors affecting transpiration, guttation and bleeding. The process of photosynthesis, carbon cycles and topics related to it are explained in detail in Chapter 6. Chapter 7- Chemical Coordination in Plants includes topics related to hormones and their functions.
ICSE class 10 Biology syllabus Unit 3: Human Anatomy and Physiology
The remaining chapters, from 8 to 14, come under unit 3. Chapter 8 covers concepts such as properties and functions of blood, circulatory system, blood transfusion and blood groups, whereas Chapter 9 gives a brief introduction to the different excretory organs and includes topics related to the kidneys and the functions of the nephron. In chapter 10, topics such as brain and spinal cord, reflex action and neurons are well explained. Chapter 11 gives in-depth knowledge about our sense organs, especially the eyes and ears. Topics based on adrenal, pancreas, thyroid, pituitary, endocrine and exocrine glands are covered in Chapter 12 of the ICSE Class 10 Biology syllabus.
Chapter 13 covers wide information about reproduction in humans, the menstrual cycle, pregnancy, etc. Topics related to theories of evolution given by various scientists, human evolution, and human ancestors have been explained in Chapter 14 of the ICSE books.
ICSE 10 Biology paper pattern
The paper pattern of the Biology paper for Class 10 is similar to that of chemistry and physics. It is important for students to know the ICSE Class 10 Biology syllabus, examination paper pattern, and the marking scheme before the examination. This will help them to know the crucial concepts and repetitive questions.
